Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method and apparatus for wrapping fish meat such as kamaboko, paste products such as vegetables, or solid foods such as sweets in bamboo leaves.

BACKGROUND OF THE INVENTION Traditionally, kamaboko (fish cakes) have been sold wrapped in bamboo leaves in order to distinguish them as souvenirs or to give them a sense of luxury. In this case, for example, a flat rectangular kamaboko 1 that has been primarily wrapped in paper or resin film, etc.
As shown in FIG. 10, it is generally wrapped in a bamboo leaf 2 and then wrapped with a band 3 such as paper tape on which the product name, vendor, etc. are printed. Traditionally, wrapping kamaboko with bamboo leaves was done manually by workers.

Problems to be Solved by the Invention As mentioned above, conventional packaging of kamaboko with bamboo leaves was done manually, requiring a large number of workers and resulting in high packaging costs.

The reason why traditional packaging was done by hand is that not only the shape and dimensions of bamboo leaves are not constant, but also the thickness and flexibility of the veins and mesophyll of a single bamboo leaf. They have different properties, and the kamaboko to be packaged are also soft and vary in size, making it extremely difficult to mechanize and automate the packaging.

The present invention was made against the background of the above circumstances, and provides a method and device that can mechanize and automate the work of wrapping soft solid foods, such as kamaboko, in bamboo leaves without manual intervention. The purpose is to

Means for Solving the Problems The method for packaging solid foods such as bamboo leaves according to the first invention of the present application is to place bamboo leaves on a base having a recess formed on the upper surface into which a solid food such as kamaboko to be packaged can be inserted. By placing the bamboo leaf so that its center is located above the concave part and pushing the solid food into the concave part from above the bamboo leaf, the bamboo leaves on both sides in the longitudinal direction and both edges in the width direction are solidified. The entire solid food is made to stand up between the side of the food and the side wall of the recess, and then one end and the other end of the bamboo leaf in the longitudinal direction are sequentially folded over the top of the solid food. The solid food wrapped in bamboo leaves is then removed from the recess.

Moreover, the bamboo leaf packaging device for solid food according to the second invention of the present application has a base having a recess formed on the upper surface into which a solid food such as kamaboko to be packaged can be inserted, and the base is arranged along a predetermined transfer path. The conveyance path includes a feeding mechanism that supplies the solid food onto the bamboo leaves on the base, and a feeding mechanism that supplies the solid food onto the bamboo leaves on the base. a pushing mechanism that pushes the bamboo leaves into the recess; a first folding mechanism that folds one longitudinal end of the bamboo leaf that has risen up on the base due to the pushing; and a first folding mechanism that folds the bamboo leaf that has risen up on the base A second folding mechanism for folding the other longitudinal end side toward the upper surface of the solid food, and a removal mechanism for removing the solid food wrapped in bamboo leaves from the concave portion of the base, are provided in that order. .

Function: In the packaging method of the first invention of the present application, a base having a recess formed in the upper surface into which a solid food such as kamaboko to be wrapped with bamboo leaves can be inserted is effectively used to wrap the solid food using bamboo leaves. Wrapping is performed. That is, a bamboo leaf is placed on a base so that the center of the bamboo leaf is located above the recess, and the solid food is pushed into the recess from above the bamboo leaf. As a result, the bamboo leaves are bent along the inner wall surface of the recess. That is, the portions on both sides in the longitudinal direction and both edges in the width direction of the bamboo leaf stand up between the side wall of the recess and the side surface of the solid food that has been pushed into it. After that, if one longitudinal end and the other end of the bamboo leaves are folded over the top of the solid food, the entire solid food will be wrapped in the bamboo leaves, and the state will change accordingly. If you remove it from the recess, you will get solid food wrapped in bamboo leaves.

As mentioned above, by simply pushing the solid food from above the bamboo leaf on the base into the concave part of the base, both sides of the bamboo leaf in the longitudinal direction and both edges in the width direction are removed from the solid food. It can be bent so that it stands up almost along the side, and once this first step is completed, one end of the bamboo leaf in the longitudinal direction and the other end can be bent over the top of the solid food. Since wrapping with bamboo leaves can be completed simply by applying a simple operation of sequentially bending the leaves to the sides, each operation can be easily mechanized and automated.

In the packaging device of the second invention, the device in which the recessed portion is formed as described above is configured to be moved along a predetermined transfer path, and the above-mentioned steps are automatically performed sequentially on the transfer path. ing. That is, first, the solid food is supplied onto the bamboo leaves placed on the base by the feeding mechanism, and then the solid food is pushed into the recess by the pushing mechanism from above the bamboo leaves. As a result, the solid food is pushed into the recess, and at the same time, as already mentioned, both longitudinal and widthwise edges of the bamboo leaf stand up between the side walls of the recess and the sides of the solid food. Both ends in the longitudinal direction extend onto the base and stand up.

Next, the top side of the bamboo leaf in the longitudinal direction and the other end side of the bamboo leaf raised on the base are sequentially folded into the upper surface of the solid food by the first folding mechanism and the second folding mechanism. By bending it to the side, the solid food becomes completely wrapped in bamboo leaves.

Incidentally, after the solid food wrapped in the bamboo leaves is removed from the recess of the base as described above, a band-like material such as tape may be wrapped around the entire food to fix it. Further, the operation of supplying the bamboo leaves onto the base may be performed manually or automatically.

2D hardly extends to the upper surface side of the base 1o since the width W2 of the bamboo leaf 2 is determined as described above, but both end portions 2A and 2B in the longitudinal direction extend above the base 10. The state will be as follows. Note that when pushed in in this way, the bamboo leaves 2 have to overlap at the four corners of the solid food 1, but in the illustrated example, the notches 11B at the four corners of the recess 11
It functions as a relief for the overlap of the bamboo leaves 2, so that even the four corners can be neatly folded.

Thereafter, as shown in FIGS. 2(E) to 2(F), both longitudinal ends 2A and 2B of the bamboo shoots 2 extending on the base 10 are sequentially folded toward the upper surface of the solid food 1. After the entire solid food 1 is wrapped in the bamboo leaves 2 in the recess 11 of the base 10 in this way, the base 1o is turned over and a knock pin is inserted into the pin hole 11G as shown in FIG. 2(G), for example. 12 is inserted and the knock pin 12 presses the solid food 1 wrapped in bamboo leaves in the recess 11 from the bottom side, and the solid food 1 wrapped in bamboo leaves can be taken out from the recess 11. After this, for example, as shown in Fig. 2 (F), a band 3 such as a tape with the product name and vendor etc. printed in advance is wrapped around it, and both ends are joined as appropriate to complete the packaging. do.

FIGS. 5 and 6 show an example of an apparatus for carrying out the method of the present invention, that is, an apparatus according to an embodiment of the second invention.

In FIGS. 5 and 6, a base 10 having the above-described configuration is shown.

The supply rotor 25 is rotated by a rotation drive mechanism 25A such as a motor, and the solid foods 1 are inserted one by one into the recess 24 at the upper position from the cutting device 26. The solid food 1 inserted into the recess 24 moves downward while being prevented from detaching by the support plate 27 as the supply rotor 25 rotates, and leaves the recess 24 at the lowest part of the supply rotor 25. It is placed on the bamboo leaf 2 on the base 10, and as the base 10 moves to the right, it moves to the right while being placed on the bamboo leaf 2.

A pushing mechanism 28 is disposed on the right side of the supply mechanism 23 (supply rotor 25). This pushing mechanism 28 is composed of a pusher rod 29 for pressing the solid food 1 on the bamboo leaves 2 downward, and an elevating drive source 30 such as a fluid pressure cylinder for elevating the pusher rod 29. By operating the lifting drive source 30, the pusher rod 29 moves the solid food 1 to the base 10.
It is designed to be pushed into the recess 11 of the. By such pushing, the bamboo leaves 2 are also pushed into the recesses 11 as described above.
It is pushed in and stands up with its one longitudinal end 2Δ and the end 2B on the usage side extending above the base 10 (see FIGS. 2(D) and 3).

On the right side of the pushing mechanism 28, a driving source 32 such as a motor is provided as a first folding mechanism 31 for folding one end 2A of the bamboo leaf 2 in the longitudinal direction onto the upper surface side of the solid food 1.
An endless annular belt 33 is provided which is rotated by. As shown in detail in FIG. 7, this endless annular belt 33 is connected from the side of one end 2Δ in the longitudinal direction of the bamboo leaf 2 to be folded with respect to the direction of movement of the base 10 onto the base 10 (therefore, the solid food 1), and as the base 10 moves forward (the solid food 1 moves forward), one end 2A (the rising part) of the bamboo leaf 2 in the longitudinal direction gradually moves forward. It is configured so that it can be pushed and folded onto the top side of the solid food 1.

To the right of this first bending mechanism 31, that is, in front of the endless annular belt 33, there is a first guide for holding the end portion 2A of the bamboo leaf bent by this belt 33 in the bent state. 34 is provided on the upper surface side of the base 10 in parallel to the direction of movement thereof.

On the right side of this belt 37, there is a second belt for holding the end portion 2B of the bamboo leaf 2 folded by the belt 37 in that state.
A guide 38 is provided on the upper surface side of the base 10 in parallel to the direction of movement thereof.

At the right end of the conveyor 20, that is, at the right end of the transfer path 21 of the base 10, the base 10 is reversed so that the recess 11 side faces downward. The removal mechanism 40 for ejecting the solid food 1 wrapped by the bamboo leaves in the recess 11 from the recess 11 includes the aforementioned knock pin 12 and a fluid pressure cylinder or electromagnetic cylinder for moving the knock pin 12 forward and backward. A forward/backward driving source 41 is provided. The dowel pin 12 is inserted into the pin hole 11C of the base 10 from the back side (that is, the top side) of the base 10 in an inverted state (see FIG. 2 (G)).
The solid food 1 wrapped in bamboo leaves 2 is pushed out from the recess 11 downward by moving forward and backward. Below this extrusion position, a table 42 for winding the strip is disposed. This table 42 is provided with a plurality of winding bases 43 near the outer peripheral edge of the wall surface at intervals in one direction of the circumference. The wrapped solid food 1 (wrapped with bamboo leaves 2) is dropped into the recess 43A at the center of the stand 43. As shown in detail in FIG. 8, each winding table 43 has grooves 438143C formed on both sides of a recess 43A that accommodates the solid food 1 to hold the strip 3. Place the strip 3 over the grooves 43B and 43C,
It is configured such that both ends of the strip 3 can be raised by dropping the solid food 1 into it.

Then, both ends of the thus raised strip 3 may be bent toward the solid food 1 wrapped in bamboo leaves, and the ends may be glued together as appropriate.

In the apparatus of the above embodiment, the bamboo leaves are manually placed one by one on the base 10 in the bamboo leaf supply section 22, but in some cases, the bamboo leaves may be automatically fed and placed. Of course, it may be configured as follows.

Furthermore, in the above-described embodiment, the belt 33 of the first folding mechanism 31 and the belt 37 of the second folding mechanism 35 are configured to rotate in synchronization with the forward movement of the base 10. Depending on their belt 33.3
Similarly to 7, a fixed guide provided on the base 10 obliquely with respect to the traveling direction of the base 10 may be used instead.

Furthermore, these bending mechanisms 31 and 35 are arranged such that the ends 2A of the bamboo leaves 2 are folded, for example, by a plate that falls down from the side of the base 10.
, 2B may be bent.

Further, in the illustrated example, the part around which the band-like body 3 is wound is manually wound and bonded, but depending on the situation, the winding may be performed automatically. For example, as shown in FIG. 9, the solid food 1 wrapped in bamboo leaves 2 is placed from the base 10 into the recess 46 of the wrapping table 45, which has a strip wrapping path 44 cut out in the center. The belt-shaped body 3 may be wound by a known winding machine through the belt-shaped body winding path 44. In this case, the ends of the strips 3 can be bonded together by heat sealing, adhesive bonding, or the like.

Effects of the Invention According to the method of the present invention, the solid food can be formed into both longitudinal and widthwise edges of the bamboo leaf by a simple operation of pushing the solid food into the concave part of the base from above the bamboo leaf. After that, the solid food can be wrapped around the solid food by simply folding the raised longitudinal ends of the bamboo leaves towards the top of the solid food. The packaging of solid foods can be easily mechanized and automated, and even if the solid foods have some dimensional errors, they can be packaged without any particular problem.

Furthermore, the device of the present invention actually applies the above-mentioned method, and
It is possible to save labor in packaging solid foods using bamboo leaves and significantly reduce packaging costs.
